Ideally, you should go across the scales 3 times with the passengers and cargo in the same position each time
1. Truck and trailer with spring bars.
2. Truck and trailer without spring bars.
3. Truck alone. I just drop my trailer in the back lot while doing that.....nobody has even complained.
Not knowing what your truck alone front axle weight is, it is a little hard to determine how the WDH should be setup. My initial thought is that you probably need some more wight distributed to the front axle.
